No offence taken.....but I have stipulated that my mechanic will be doing the work not me..... :D

Much prefer him, just so i dont kill myself!!!

350 Chev must be able to fit legally because there are other examplesd of this being done.......correct me if i`m wrong!!!

Injected 5 litre might also be the go, but its still the same amount of work, so why wouldnt you go the 5.7 if you can.......and it cant be that much heavier on fuel when comparing.

I have decided and there will be a V8 in there, but i just need to decide what engine....will be auto though............maybe some opinions on what engine people think then???

Seriously talk to the engineer, it varies from State to State, in Vic you can run a 350, Queensland is only a 307 and I think NSW is the same. As for Tassie?????

To save on headaches and un-needed expenses get an engineer on board early. Most of my mates who have done SBC conversions in earlies did and it saved them re-doing things and solved a few uncertanties.
Speed and Style........... One day I'll get the speed bit.

Don't know if you've done this already or not but before you start spending any $$$ it might pay to see the tassy rego authorities and/or an engineer to see if what you want to do is OK by them.

Here in N.S.W if one goes by the RTA rules,verbatim, the biggest capacity engine allowable in an FB is 332 cubes ( I had a look yesterday and used to formula on the DOTARS site ).

Although,that said,there are a few cars around with bigger engines.Seems to depend on what mood the engineer is in at times and whether he is willing to bend the rules.

Not trying to be a smart arse, just trying to help save you some $$$ and wasted time if you haven't already checked with the authorities.

I dont think your being a smart arse, I think its sensible and i will certainly have a chat with an engineer....I know down here they are pretty good........so just wait and see!!!

So what engine do you guys think/recommend.....I like the idea of the 5.7 but what about you guys???

502 Crate motor. Methanol.





Seriously,

There's a plethora of good engines out there that offer great bang for the buck if you can't go the large V8 route.....

Barra6T, 2JZGTE, RB26/30, 4G63, SR20DET. All are solidly built engines capable of large horsepower and good fuel consumption.

I'm a bit of an old fart and like the old carbied engines as they are easy to work on...... at least for old farts!!

So, I like carbied Holden or Chev V8's.Gives them that "OLD SKOOL" look ( as the youngins now call it ).

Don't really need any of that new fandangled diagnostic gear to fix them when they play up like the modern fuelly engines need.

Really depends on what sort of style of car you are looking at doing I suppose.

Old Skool look ( there's that word again ) would probably go with a simple older V8.

Blinged up car would probably go with one of them Gen III engines.

If I was going V8 in one of my cars my choice would be Chev ( carbied )mainly because parts for them are available everywhere and they are reliable.I do like the idea of a Holden V8 as well and again, there is still a pretty good parts supply and they aren't a bad motor to work on.

Thats my choice and its all about what YOU want to do.

Altimately it's your car and the only person that has to be happy with it is you.

Cheers,

Terry.

Hey cam its starting to sound like you have made up your mind thats ok.I rekon you could have more real estate problems with a gen 3.The trouble is you wont know until you get one.That firewall will probable need more alterations.The p/steer,aircon and alternator take up alot of room.I know i had to cut a bit of the front out to make a bit of room.That was with a short nose water pump.Are they available for gen 3 blocks?On mine the steering and the starter motor is on the same side making near imposible to fit pipes.Are gen 3 starters on the drivers side aswell?Its alot of hard work just writing what to do.I would tick the box with the injected 5 litre.But its your car.your choice.Wait till you have to start picking colours,thats when the hard decisions need to be made.

i only said injected 5 litre for cheaper original purchase, if you use early vn/vp type motor/box electricals are reasnoably easy
but if you have a $30,000 budget you should be able to get the 5.7 done depending on rego specs
but you could do the injected 5 litre for about $10,000 leaves you $20,000 to spend on the rest of the car and fuel
miss piggy, you should have yor early holden rights revoked the mere thought of a jap engine in an early holden :evil: :evil: :evil: :evil: :evil: i don't care how good they go

LOL Ratbox.

There's an FC in Newcastle with an SR20DET conversion. I love it. I have a built 1JZ (2.5L Twin Turbo) sitting in my shed that was originally intended for the EK.

But I love the grey powered EK. Wouldn't have it any other way. Probably my favourite car to drive. I've even gone off a 186 conversion.

I have a Mitsubishi Evo 9 for going fast. Nothing much comes close to it.

All of my mates have no idea how I can own both an EK and a late model Jap performance car as well as a late model V8. Everyone I know is either one or the other. My wife calls me the "MOTOR Magazine Anti-Christ". She's such an old Holden tragic it's not funny. If she had it her way, the garage would be full of FE-EK holdens.

They're just missing out.

yes i'm the first to embarassingly admit them jap things go :shock: :? :oops:
if i had one of those evo whatsy thingys, had would be the correct term and i would have a garage full of FB/EK's :D one of which in a straight line would scare a evo sometinorother to death :D
saw a camaro on telle the other night twin turbo small block 1580hp, 1500 and something ft/lb of torque :shock: and you can drive it in daily traffic :shock: had it lined up against a 4rarri camaro passed the 4rarri with the tyres blazing like the 4rarri put his breaks on :) :) :)

The 5.7 litre would be nice, and I am seriously thinking about it, but yeah the injected 5 litre could be nice also!!!........but whats going to be better for everyday driving??? Any difference???

Colour has been chosen........i think!!!! :shock: but this could all change!!!

Funny enough, i want to keep the outside appearance "Old Skool" because i dont want to let on to whats under the bonnet and also because i love that look!!!

I dont know if i have said this before, but everyone on here is great and i love being able to bounce these ideas around.......just wanted to say thanks!!! :D

I wouldn't rule out a 1UZFE option either. (ie 4.0l Lexus DOHC V8 ). Full front cuts can be had for under $2,000. This leaves a performance rebuild in the budget, and it's not uncommon for these engines to produce an easy 500hp after bugger all work.

At the end of the day, however, the LS1 is really the best option. Hopefully, the Tas Gov allows it. I think an LS1 is a much better daily driver than an injected 5.0. Especially if you give the 5.7 a cam.

The Lexus donk is quite wide, dont know how you would go getting one in an EK - but you are right about how easy it is to get some horsepower out of them.
I started with nothing and still have most of it left.

True,

They're a fair size. But around 40% lighter than a 5.0l

there was an EH ute at tug in the park with i think a lexus V8 in it it had toyota on it so i guess it was, if it will go in an EH it will go in an FB/EK
as to what engine you use you would probably get more power from the 5.7 IF yor allowd to use it but the conversion will cost atleast double what you'de spend with the 5 litre option
5.7 to buy all that you need $5000-$7000 then start on conversion
5 litre holden $1000-$2000 for 5 litre vn-vp doner car, you could prolly do the whole 5 litre holden conversion for the cost of the parts alone for the 5.7
as yor talking a daily driver the 5 litre will have more power than you will ever use and be cheaper if not the same to run as the 5.7
